推荐答案

我并不惊讶它不起作用-我会如果确实如此，那一定会感到惊讶(甚至感到难过).

想一想您要做什么:

通过互联网从本地PC读取文件文件，并将其写入世界上其他地方的计算机的指定文件夹，指定硬盘驱动器中."

如果您可以轻松地做到这一点，那么什么会阻止我这样做呢?并使用远程服务器进行Internet备份或文件共享设备?如果它填满了一点，请删除您的文件以为我留出空间?

如果要这样做，则需要查看在软件和服务器之间建立FTP连接(假设已将其配置为接受FTP请求)并以这种方式传输文件. Google可以在这里为您提供帮助-它找到了以下内容: C#FTP客户端库 [ ^ ]

I''m not surprised it doesn''t work - I would be amazed (and rather saddened) if it did.

Think for a moment about what you are trying to do:

"Read file file from your local pc, and write it to a specified folder, of a specified hard drive, of a computer somewhere else in the world, via the internet."

If you could do it that easily, what would stop me doing the same? And using your remote server for an internet backup, or file sharing device? And if it filled up a bit, deleting your files to make room for mine?

If you want to do that, then you need to look at setting up an FTP connection between your software and the server (assuming it is configured to accept FTP requests) and transfer the file that way. Google can help you there - it found this: C# FTP Client Library[^]
